[Brief explanation of the drawing]

Fig. 1 is a schematic plan view of the plate-making device, Fig. 2 is a partially cutaway schematic front view of the exposure machine, Fig. 3 is a partially cutaway schematic side view, and Fig. 4 shows the main parts of the exposure machine. Fig. 5 is an enlarged partially cutaway front view of the baking frame with the cassette frame set and lowered toward the surface plate, Fig. 5 is an enlarged partially cutaway side view, Fig. 6 is a cross-sectional plan view, and Fig. 7 is the film. FIG. 8 is an enlarged cross-sectional view taken along the line -- in FIG. 7, and FIG. 9 is an enlarged cross-sectional view of essential parts of the film cassette frame. 1 is a plate material, 3 is an exposure machine, 4 is a surface plate, 5 is a negative film, 6 is a translucent sheet, 7 is a film cassette frame, 9 is a printing frame, 17 is an exposure light source, 43 is a positioning hole, 45 is a transport mechanism, 46 is a detector, 47
is a positioning pin, and 49 is a frame.

Claims (1)

[Scope of utility model registration request] Between the surface plate 4 on which the photosensitive plate material 1 is positioned and placed and the exposure light source 17 disposed above it,
A rectangular frame 49 that can be raised and lowered with respect to the surface plate 4
A printing frame 9 to which a film cassette frame 7 made of a transparent sheet 6 on which a negative film 5 is pasted is mounted is provided, and the printing frame 9 allows the film cassette frame 7 to be inserted from one direction. In the exposure machine 3, which is configured to be able to be pulled out in the other direction, positioning holes 43 are formed at both ends of the frame body 49 of the film cassette frame 7, and the film cassette frame is inserted into the printing frame 9. a transport mechanism 45 for transporting film cassettes 7 into the film frame 9 while positioning them in a direction perpendicular to the direction of movement thereof, and transporting the film cassettes from the film frame 9; and a film cassette carried into the film frame 9 by the transport mechanism 45 A detector 46 that detects the position of the frame 7; and a positioning pin 47 that is inserted into the positioning hole 43 to position the film cassette frame 7 at a predetermined position within the printing frame 9 when the detector 46 detects the position of the film cassette frame 7. A positioning mechanism for a film cassette frame in an exposure machine, characterized in that a film cassette frame positioning mechanism is provided in an exposure machine.
